水稻收割期间遇连阴雨,脱粒湿谷无法晒干,容易发热、霉变和生芽,造成损失。特荐以下应急处理方法: 1.薄膜覆盖密封处理法 在禾场或室内地面垫一层塑料薄膜,将湿谷倒在薄膜上,以粮堆大小1000～3000千克、堆高不超过1米为宜,粮堆上再盖一层塑料布,塑料布边缘用粘性泥土或黄沙压严实。其机理是:湿谷在密封条件下,在呼吸过程中消耗了膜内氧气,二氧化碳便大量积累,起到了抑制湿谷发芽和霉变的作用。采用此法处理湿谷,种子含水量在25％以下可密封7天,含水量在30％以下可密封5天,含水量在35％左
During the harvest of rice, even if the rainy season, threshing wet valley can not be dried, easy to heat, mildew and germination, resulting in loss. Special recommended the following emergency measures: 1. Film cover sealing method In the threshing floor or indoor floor pad a plastic film, the wet valley on the film, the size of the grain heap 1000 ~ 3000 kg, heap height of not more than 1 m is appropriate , And then covered with a layer of plastic sheeting on the piles of foodstuffs. The edge of the plastic sheeting should be compacted with clay or yellow sand. The mechanism is: Wet Valley in the sealed conditions, the process of breathing oxygen consumed in the membrane, carbon dioxide will be a large accumulation, played a role in inhibiting the wet valley of germination and mildew. Using this method to treat wet valleys, the seed moisture content can be sealed under 25% for 7 days, the water content below 30% can be sealed for 5 days and the water content is about 35%
